What conclusion can be drawn from embryological development? Insect and bird wings are similar in function but not in structure. Paleontologists have used fossils to trace the evolution of the modern camel. Many organisms have structures with no apparent function found during embryo development. The presence of gill slits and tails in early vertebrate embryos shows that they may share a common ancestor.
